Milter-greylist

Hi all -

I am using clamav-milter, spamass-milter, and milter-greylist 1.6.

I am not an m4 expert by any stretch of the imagination.  My sendmail.mc
file looks like this:

dnl INPUT_MAIL_FILTER(`greylist',`S=local:/var/milter-greylist/milter-
greylist.sock')dnl
define(`confMILTER_MACROS_HELO', `{verify}, {cert_subject}')dnl
define(`confMILTER_MACROS_ENVFROM', `i, {auth_authen}')dnl

INPUT_MAIL_FILTER(`spamassassin', `S=local:/var/run/spamass.sock, F=,
T=C:15m;S:4m;R:4m;E:10m')dnl
define(`confMILTER_MACROS_CONNECT',`b, j, _, {daemon_name}, {if_name},
{if_addr}')dnl

INPUT_MAIL_FILTER(`clamav-milter', `S=local:/var/run/clamav/clamav-
milter.sock, F=T,T=S:4m;R:4m;E:10m')

I have simply done what the INSTALL or README docs for each of the
milters tells me to do.

Now I notice that milter-greylist 2 tells me to add this to my
sendmail.mc file:

INPUT_MAIL_FILTER(`greylist',
`S=local:/var/milter-greylist/milter-greylist.sock')
define(`confMILTER_MACROS_CONNECT', `j, {if_addr}')
define(`confMILTER_MACROS_HELO', `{verify}, {cert_subject}')
define(`confMILTER_MACROS_ENVFROM', `i, {auth_authen}')
define(`confMILTER_MACROS_ENVRCPT', `{greylist}')

This will put different settings for confMILTER_MACROS_CONNECT and
confMILTER_MACROS_HELO into my sendmailmc file.  I can't imagine that is
a good thing.

Can someone who understands milters better than me give me a layman's
explanation of what all these conf* entries in sendmail.mc are so I can
make a decision about what to do when I run into conflicting
instructions like this?

Or, if you know of a good FM to R that can explain this in a way that a
non-programmer, non-sendmail guru can understand, that would be great as
well.

Thanks!
Thomas

I'm not a sendmail guru, the people at work think I am.

The MILTER_MACROS definitions say what information is passed from
sendmail to the milter when it is called at different stages of an SMTP
conversation.  You want each macro set to contain all information
required by each milter, so you would use

    INPUT_MAIL_FILTER(`clamav-milter', `S=local:/var/run/clamav/clamav-milter.sock, F=T,T=S:4m;R:4m;E:10m')
    INPUT_MAIL_FILTER(`greylist',`S=local:/var/milter-greylist/milter-greylist.sock')dnl
    INPUT_MAIL_FILTER(`spamassassin', `S=local:/var/run/spamass.sock, F=,T=C:15m;S:4m;R:4m;E:10m')dnl
    define(`confMILTER_MACROS_CONNECT',`b, j, _, {daemon_name}, {if_name}, {if_addr}')dnl
    define(`confMILTER_MACROS_ENVFROM', `i, {auth_authen}')dnl
    define(`confMILTER_MACROS_ENVRCPT', `{greylist}')
    define(`confMILTER_MACROS_HELO', `{verify}, {cert_subject}')dnl

to be able to use all three milters.
